ELECTRIC-SIGN BECEPTACLEQ Latinos.

To all whom it may concern Be it known that L-RQMNALD M. FRY- nnrorrowroz, a citizen of the United States, residing at Stevens Point, in the county of Portage, State of WVisconsin, have invente a new and useful Electric-Sign Receptacle; and I do hereby declare the tollowing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the. same.

This invention pertains to electric light receptacles in general, but is particularly a receptacle for use with electric signs or the like.

The principal object of the invention is to provide a receptacle in which the vital parts will be protected from the weather.

-A second object of the invention is to combine in a device of this character general security and simplicity of structure, and to this end, an outer containing shell is provided in which a pair of lamp bases may be firmly secured.

As a third object, the device makes provision for attachment to a conduit carrying electric wires and for the quick and effective attachment of the electrical supply means to their proper contacting points on thelamp bases.

Practice may require some changes from the design herein shown, and the, right is claimed to make any that do not depart from the spirit of the subjoined claims.

The same numerals of reference designate the same parts throughout the several'figures of the drawings, wherein Figure 1 is a plan view showing the device as a means for carrying the illuininants of an electric sign.

Fig. 2 is a side elevation of the receptacle.

Fig. 3 is a sectional view on line 33 0 Fig. 2.

Fig. Fig. 2.

Fig. 1 shows the channel pieces '2 and having the rods 3 for suppoiting them on the front of a building or at any other place where the signs may be on display. The conduit 1 carrying the wires 5 supports the receptacle by connecting with its threaded nipple 6. The-lamps 7 arezheld by the receptacle which also ho ds the reflect0rs'8. that are adjustable concentric with the lamps. In Fig. 1 the two reflectors 8 appear in difier- 4: is'a sectional view on line H of Specification of Letters Patent.

ent relative positions. This is to show that these reflectors may be positioned so as to obtain the best reflection of the lights 7.

In the receptacle itself, the nipple 6 is integral with the outer containing casing 9, which is adapted to contain the lamp sockets, with the insulating sleeve 10 intervening between them and the outer casing 9. The socketshave the insulating bases 11 upon which the shells 14: are held, the

shells 14 being adapted to receive the conventional lamp base. One shell 14 carries as integral parts thereof the cylindrical bosses 12 and 13, while carries similarly the cylindrical bosses 15 and 16. Bosses 15 and 16 have threaded holes in their centers screws 17. Through their centers the bases 11 have the contact studs 18 with their enlarged heads 19 and their bottom portions 20. When the bases are together the two bottom portions 20 form a globular shaped piece with the hole 21 through its center.

I The nipple 6 has a hole 2 1 longitudinally through its center and this hole opens into the interior of the casing 9 through the cylindrical projection 22. A hole in the insulating sleeve 10 through which a projection 22 protrudes enables the former to be held in place within the casing 9. On their periphery the bases 11 are counterbored to make room for the projection 22, half of the counter-boring being in one half in the other. Recesses 25 are formed in the 11 which recesses (when the two bases 11 are together) form tion of the hole 24. Recesses 23 emanate from recesses 25 and terminate between the bosses 16 and 13. Recesses 23 and 25 with a hole 21 in the nipple provide means for bringing the conducting wires to the connection points on the lamp sockets.

In practice the device is attached by its nipple 6 to any suitable conduit carrying electric conducting wires. The hole 24'. then admits the wires into casing 9 and the recesses and 23 permit one wire to be clamped at 21 between the two feet 20 and the other to be clamped between the bosses 13 and 16, It will be seen that the screws 17 operate to perform this clamping function, the hole 21 and the space between the bosses 13 and 16 being of the proper diameter and widthrespectively to effectively hold the wires bethe other shell 14' base 11 and a continuaand bosses 12 and 13 have similarly disposed body holes for the.

tween them. When the bases are clamped together the counterbored hole in their periphery engages the projection 22 snugly and thus holds them and the socket shells 14 which they support firmly in position within the outer casing 9. The method of vconnecting the conducting wires to the lamp sockets prevents damage to the former from the elements and particularly adapts this device as a receptacle for signs, it being understood that the signs used shall be of any conventional form wherein illuminants are employed to distinguish the lettering.

What is claimed is '1. In an electric sign receptacle, an outer casing having a nipple integral therewith and a projection on its interior where the nipple opens into it, an insulating sleeve adapted to be held in place by engagement with said projection, a pair of lamp sockets similarly secured by said projection, and means for simultaneously securing electric conducting wires to the proper parts of the lamp sockets when securing said lamp sock- 25 pts in position.

2. In an electric sign receptacle, an outer casing having a nipple integral therewith and a projection on its interior where the nipple opens into it, an insulating sleeve adapted to be held in place by engagement with said projection, and a pair of lamp sockets similarly secured by said projection, each of said sockets comprising a corrugated cylindrical shell having diametrically disposed cylindrical bosses integral therewith, an insulating base, a central contacting stud and threaded means by which it may be attached to the base of the other socket so that the pair of sockets may be locked in position onthe aforesaid projection and clamp electric conducting wires between the contacting studs and the cylindrical boss respectively.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses. ROMNALD M. FRYDRYGHOWIGZ. Witnesses:
